Fraction of the Dark Current Carried by Ca(2+) through Cgmp-Gated Ion Channels of Intact Rod and Cone Photoreceptors
The selectivity for Ca(2+) over Na(+), PCa/PNa, is higher in cGMP-gated (CNG) ion channels of retinal cone photoreceptors than in those of rods. To ascertain the physiological significance of this fact, we determined the fraction of the cyclic nucleotide–gated current specifically carried by Ca(2+)...
